Application filed January 10. 1905. Serial No. 240.428. v

To all whom it may concern:

Be it known that I, HERMAN HOLLERITH, a

citizen of the United States, residing in Garrett Park, Montgomery county, Maryland,

have invented certain new and useful -Im-' rovements in Apparatus for Use in Tabulatr mg and other Like Systems, of which the following is a full, clear, and exact descriptlon, reference being had to the accompanying drawings, forming part of this specification.

ThlS invention relates, primaril to means andapparatus'for use inthe Hol erith tabulating system; and the principal object of the invention is to provide means by which themeans of the record index-points.

My invention also comprises novel means for presenting the records successively to the record-actuated circuit-controlling means or their equivalent. L

I have selected for the purposes of illustration and description an apparatus which embodies my invention in a preferred form, and

an arrangement of electric'circuits adapted bodying my to be used with the tabulating-re isters shown and described in my United tates Letters Patent No. 677,214, dated June 25, 1901, to which reference is made for a further description of the construction and mode of operation of said registers; but is to'be understood that my inventionis not limited to the particular form of a paratus herein shown or to its use for ta ulating alone, since it may be employed in connection with other app aratussuch, for instance, as that described in my United States Letters Patent No. 685,608, dated October 29, 1901, and No. 777,209, dated December 13, 1904, as well as for the verification of the records either before or after tabulation.

In the drawings, Figure 1 is a side elevation, viewed from the right, of an apparatus eminvention. Fig. 2 is a plan I thereof. '-F1g. 3 is a side elevation, viewed from the left, oftheRcord-releasing devices. Fig. 4 is a plan view thereof. Fig. 5 is a front elevation of the circuit-controlling devices which are actuated at each operation of the apparatus. Fig. 6 is a front elevation, partly in section, of the pin-box and cooperating arts. Fig. 7 is an enlarged section of one o the record-actuated contact devices carried by the pin-box. Fig.8 is an enlarged cross-section thereof on the line as m, Fig. 7; and-Fig. 9 is a diagrammatic view showing thegeneral arran ernent of the circuits as the apparatus is use for-tabulating in conjunction with the re isters described in my said Letters Patent 0. 677,214.

Similar-reference characters are employed to designate like parts in all the views.

The particular form' of apparatus illustrated in the drawings comprises two stand-' ards 1, which are secured to a horizontal table or support 2 by the screws 3. Studs 4 roject from the standards 1 and form guides or the cross-head 5, which carries the platen or card-plate6, which, with its cooperating parts to be described, constitutes a record carrier. Connecting rods 8, supported in suitable bearings 9, are connected at one end with the cross-head 5 and at the op osite end with the links 10, which are pivotal y secured to the connecting-rods 8 and to the rockarms 11, mounted on the shaft 12. The rock-arms 1-1 are slotted to receive the sliding block 14, pivotall secured to the gear 15, which meshes with t e driving-pinion 17011 the shaft 18, driven by a motor M. When operated in connection with the apparatus illustrated in my said Patent No. 677 ,214,-the gear 16 is arranged to revolve in synchro- IllSIIl with the gear 74 of said patent. As will 15 will effect one reciprocation forward and; back of the cross-head 5 and card-plate 6. I

A pin-box consistin frame 20 is removably ca now be understood, one revolution of the gear of a rectangular mped in the standards 1 by the thumb-nuts 21. I A pressure- 1 plate 23 is carried in front .of the pin-box 20 y studs 24, slidably mounted in the pin-box, and coil- Brings 25, carried by the studs 24 between t e face of the pin-box and the pressure-plate 23, yieldingly support the-latter. The pin-box 20 carries a plurality of record actuated or controlled selecting devices comprising the spring-pressed conducting-pins 23 are provided with registering perforations 28 and 29, one for each of said pins, so that -when the card-plate -is carried toward the pimbox by the reciprocation of the crossf ead'5 it will enga e the pressure-plate and! carry it also towar the pin-box, the pins 27.

entering and projecting through the per'forations. On the return movement of the crosshead the springs 25 will return the pressureplate 23 to its normal position, while the cardplate6 will be carried to its forward limit of movement, leaving-a card-feeding space vbetween the pressure-plate and card-plate, as shown in Figs. 1 and 2. If, however, a card, or, as I prefer to term it, a record is placed between the card and pressure plates when they are carriedtoward the pin-box, the portions of the'cards which coverthe perforations in the card-plate 6 enga e the pins and force them backward, and only such pins as may re ister with perforations formed in the card wil remain in their normal positions. (Shown-in. Figs. 2 and 7.) V

The selecting devices or pins, which are generically indicated by the numeral 27 constitute the actuating element of what (since they are contactswhich are directly actuated by the unpunched portion of the record-- cards) I hereinafter refer to as record'actuated contacts and are arranged in separate groups in the pin-box and are slidably mounted at one end in conducting terminal sockets 30, which are held in the back plate 31 of insulating material, while near theropposite end they are supported in bars 32, each bar extending across the front of the pin-box. Each pin is insulated from its -bar.32 by insulatingbushings 33. ducting metal and are formed with coneshaped projections 34 on their inner edges. On each pin, Fig. 7, is secured a collar 35, and between the same and the socket 3 is a coilsprin .36. A thimble 37-, of conducting meta ,is also secured'to each pin and seats against its conical projection 34 on the'b'ar 32. The contact-piece proper is. carried b the thimble 37 and is preferably formed wit a cylindrical section 39, fitted securely to the thimble, and with a numberof resilient arms 40, which furnish a wiping contact with the ro'ection 34. Hencewhenthe pin is pushed ac into the pin-box by en agin -with an unpunchedportion of a recor -ca'-r the arms 40 will be carried away from .the projection 34; but if the pin 27 passes through a punched The bars 32 are made-of con-' hole in the card the arms 40 W'lll remain in contact with the projections 34.

Record-supports in the formof fingers 45 normally extend across the space between the card-plate 6 and the pressurelate for the purpose of supporting the recor so that the index-point positions thereon will regis-. ter vertica ly with the perforations in said plates until it is clamped between them. 1 The Y may be secured.

. to the standards 1. a are carried by the levers 61, and their points ends of the fingers downward, as shown in Fig. 3.. Atoe 48 and an arm 49 are secured to therock-shaft 46. A spring-retracted armature 51 of an electromagnet 52 is-arranged to engage the arm 49 on the rock-shaft 46 zontal position. (Shown in Fig. 1.) When therecord reaches its 0 erative position and closes the circuit throug the coils of the magnet 52, as will be presently described, the armature 51 is drawn out-of. engagement with the arm 49 and the spring 47 will cause the fing ers 45 to drop into the position indicated in ig. 3 and in dotted lines in-Fig. 9. The record is thus left unsu ported by the fingers 45; but it will be firm y clamped in position betweenthe card-plate 6 and pressurelate 23 until the backward movement. 0 the former releases it, when the record will drop 46 to carry t e arm 49 again into engagement with the armature 51, the circuit through the armature-coils having in the meantime been broken and the armature released.

For the purpose of insuring the correct horizontal reglstration of the index-point positions of the records with the perforations in the card and. pressure plates and with the pins 27., I provide centering-arms at the ends of the pressure-plate. Said arms are secured to levers 61, which are pivoted at 62 Adjusting-screws 63 are held against the standards 1 by the springs 64 when a record is in operative position.

The arms 60 work in slots 65, "formed in the card and pressure plates, and by adjusting the screws 63 exact registration of the records 3 In order to. permit the rapid feeding of the records to the a" aratus, it is essential that the arms 60 shoulii be separated when a record is fed to the apparatus/ For this purpose I v provideflthe levers 61 with arms 66, which are en aged b earns 67 fast on the connecting-r0 s 8. hen "thecard-plateis' in its forward position and a. record is to be fed to the apparatus, the arms 66 will be engaged by thecams 67 and the forward ends of the arms 60 will be sufficiently separated to per- ;mitthe convenient feeding of the records but as the card-plate is carried -towardthe pressure-plate the cams 67 will be carried f outof engagementwith the arms 66 and the springs 64 will swing the arms 60 toward each other, so as to engage one end or the other of an mcorrectly-positioned record and and hold the arms 45 in their normal or hori- I shift it horizontallyuntil the ends of the adjusting-screws 63 contact withthe standards 1. This will occur just before the record is clamped between the card and pressure plates,

so that when this occurs the index-point positions of the record will be in exact registration with the perforations in said plates.

, The main operating-circuit for the recordactuated contacts is normally open and is closed momentarily at each complete reciprocation of the apparatus by a pair of normally separated contacts consisting of two spring conducting-arms and 71, arranged at one side of the gear 15. On the gear 15 is secured a stud 72, which at each revolution of the gear, and whilethe record is in its opera-1 tive position, enga es the arm 70 and carries the contact-point't ereofa ainst the contactpoint of arm 71, holding t em together momentarily until the continued revolution of the gear 15 carries the stud -7 2 out of'engage ment with the arm 70, breaking the circuit.

The register R, of which-one section is indicated diagrammatically in Fig. 9, as will more fully appear by reference tomysaid Patent No. 677,214, is designed for the tabulation or compilation of items of value or amount, and a simplified'form of record for such Work is described and illustrated in said patent. groups each of which may com rise one or more transversely-arranged para lel columns of numerals from 0 to 9, inclusive, arranged successively from the top of the record. These numerals designate the index-point positions on the record and correspond to the position of the selecting devices or pins 27 in the pin-box. Thus the group of. pins specially indicated in the diagram Fig. 9 b' the numbers 80-89 includes the pins whic are controlled by one column of index-point positions on the record, the pin 80 representing the 0 the in 81 theindex-point position denoted by t e figure 1 ,"lmd so on successively. The pin 80 is, by conductor 90,

electrically connected with a resistance-coil 91 and each of the pins 81 to 89 is similarly connected with one of a group of electromagnets 92, which are. supported in a pair of The items thereon are divided into sector-shaped plates 93. The resistance'91 and the magnets 92 correspond, respectively, with the resistance 94 and the magnets 78, (shown and described in my said Patent No. 677,214.) When the. apparatus is in operation and the coils of one of the magnets 92' are energized, the magnet will actuate mechanism by which the item denoted by its cor- I responding index-point on the record is added to the amount appearin on' the indicators of I the register. Thus if t e circuit be closed throughthe contacts of pin 80, which represents the cipher and is connected with resistance 91, no addition will be made; but if the circuit be closed through the contacts of in' 85,which represents-the 5, five willbe ad ed tion of the to the amount shown on the indicators. The pin 94 is constructed and operates in 'substantially the same manner as the pins 80 to '89; but its purpose is, only to carrythe cur.

rent to the bar 32, and it is so arranged in the pin-box that when the record is properly ,positioned to actuate the other pins it will just clear the edge of the card and will pass freely through the perforations in the pressure and card plates and the contact between it-and the bar 32will be maintained, whileif the card be-improp erly positioned it will engage the pin 94, breaking such contact and no current will flow. to the bar 32.

With this brief but sufficient description of the operation of the registers and their actuating-magnets I will now describe the operaapdparatus herein shown, referring first to the iagram Fig. 9. The main cir- .-cuit-for all the record-actuated contacts is I normally vopen between the contacts 70 and gram, is inserted in the feed-space-between the card and pressure plates, being supported there by the fingers 45 during the forward movement of the card-plate until it is properly centered by the arms 60 and clamped'between the card and ressure. plates. It is in this position carrie further forward, escaping the ground-pin 94, and the unpunched portion of the card will enga e all the pins to 89, except the pin 85, an carry their contact-tongues back out of contact with the bar 32;.but the pin will passv throu h the punched hole, and the ton ues 40 on t is pin will remaln 1n contact wit the conical projection 34 on the bar. Then as the card reaches the inner limit of its movem'entthe" main circuit will be closed at the contacts 70 71 by' the stud 72 on the gear'15, and the current will flow through pin 94 to bar 32 to pin 85, through the coils of the magnet connected therewith, through the conductors 95 and 96, energizing the fifth magnet from the top in the series of magnets 92 and actuating the registering mechanism to add five to the amount shown on the indicators and also energizing the magnet 52, releasing the arm 49, and permitting the fingers45 to drop. On the backward or return movement of the card and pressure lates the record will'be released as soon as t e pressure-plate reaches its limit of motion, and the record thus released will drop by gravity into a suitable compartment or receptacleunder the apparatus.

Only one ground-pin 94 employed-for all the registers or other equivalent record-controlled devices used in connection with my invention, and said pin 94, the conductingbars 32, and all the groups of magnets 92 of the registers orequivalent devices are by the conductors 101 and the card-actuated con- -tacts so connected in series that if at any operation of the apparatus the contacts carried by said pin 94 or by any of the magnet-con.

trolling pins in any of the predetermined groups does not remain closed, owing, for instance, to improper centering or improper punching of the record, thecircuit through the ap aratus will remain open at the point, and t e register-indicators and record-releasing devices will not operate. I have not considered (it necessary to illustrate or describe more'than one roup of register-ma nets, since the principle of operation of allis the same and the series connection above referred to is fully understood by those skilled in the art. 7 i

For the purpose of securing brevity and.

simplicity in the foregoing description I have purposely refrained om describing numerous modifications n form ando eratlon which might obviously be made wit out in a ,volvin'g any departure from my invention; but it is not my intention that the appended claims (except where clearly limited in terms) shall exclude such.modifications or equivalents or suchfreversal of parts or action as would fall within the scope or embody the principles of my invention.

In my United States Letters Patent No. 685 ,608 hereinbefore referred to, I have illustrated and described a device for momentarily arresting the verticaLm'olement-of the record when it reaches its operative osition.

That device, however, is entirely di erent'inconstruction and mode of operation from the record-supporting device herein described and claimed, since it does not sup ort the record while the latter is being move into its operative position, nor is it directly actuated to release the record by the record-actuated contacts. Nevertheless I have in some of the a pended claims used expressions which indlcate that the releasing'device for the recordsupport is to be operated. directly by' the record-actuated. contacts in order to disdevice abovetinguish the record-arrestin referred to, which is actuate directly by the moving parts of the a paratus.
